Subject: [PATCH] Taxonomy: Correct the check for error messages in
 `wp-admin/edit-tag-form.php`.
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of checking for a specific message, e.g. “Item not updated”, the `$_REQUEST['error']` variable is now checked. This allows for custom messages added via the `term_updated_messages` filter to be considered an error when appropriate, and displayed with the correct CSS class.

This also brings consistency with a similar check in `wp-admin/edit-tags.php`.

Follow-up to [31823], [44663].

Props xipasduarte.
Fixes #61896.
